Narrative:
Taxied out of pit on a ferry flight, and performed all checklist items. After being cleared for takeoff, and advancing power levers, got a takeoff warning horn. We were very slow (well below 80 KTS) so we aborted and taxied clear of active runway. Upon investigation of all system associated with the takeoff warning horn, we found a circuit breaker had popped. This circuit breaker was associated with overhead leading edge flap indications. It was possibly popped due to first officer oxygen mask positioning. Oxygen mask was in proper hanger but positioned between first officer's seat back and circuit breaker panel. Circuit breaker was reset and system rechked for good indication. Waited precautionary 15 min for brake cooling, got rereleased from dispatch. Also contacted maintenance control foreman to confirm a return to gate and logbook write up was unnecessary.

Title: ACR MLG TKOF ABORT WITH TKOF WARNING HORN SOUNDED AS PWR WAS ADVANCED.
Narrative: TAXIED OUT OF PIT ON A FERRY FLT, AND PERFORMED ALL CHKLIST ITEMS. AFTER BEING CLRED FOR TKOF, AND ADVANCING PWR LEVERS, GOT A TKOF WARNING HORN. WE WERE VERY SLOW (WELL BELOW 80 KTS) SO WE ABORTED AND TAXIED CLR OF ACTIVE RWY. UPON INVESTIGATION OF ALL SYS ASSOCIATED WITH THE TKOF WARNING HORN, WE FOUND A CIRCUIT BREAKER HAD POPPED. THIS CIRCUIT BREAKER WAS ASSOCIATED WITH OVERHEAD LEADING EDGE FLAP INDICATIONS. IT WAS POSSIBLY POPPED DUE TO FO OXYGEN MASK POSITIONING. OXYGEN MASK WAS IN PROPER HANGER BUT POSITIONED BTWN FO'S SEAT BACK AND CIRCUIT BREAKER PANEL. CIRCUIT BREAKER WAS RESET AND SYS RECHKED FOR GOOD INDICATION. WAITED PRECAUTIONARY 15 MIN FOR BRAKE COOLING, GOT RERELEASED FROM DISPATCH. ALSO CONTACTED MAINT CTL FOREMAN TO CONFIRM A RETURN TO GATE AND LOGBOOK WRITE UP WAS UNNECESSARY.
